The cartoon is centered on Elmer Fudd, who goes to Jellostone National Park to camp out and relax. Unfortunately for him, he sets up camp by the residence of (pre-character-development) Bugs Bunny, who is annoyed by Elmer's presence and decides to screw around with him for the heck of it.
- Artistic License Biology: Granted, it is a cartoon, and Elmer only gets the term "grizzly bear" from a book, but the bear seen here is definitely a black bear, due to his color, head shape, and size (not being much larger than Elmer himself).
- Bears Are Bad News: Elmer unwittingly provokes the wrath of a bear that comes across him, and the subsequent chase makes him decide to leave the park.
- Breaking the Fourth Wall: When Bugs is tricking Elmer into walking off a cliff, he mugs to the audience "I do this kind of stuff to him all throughout the picture." Later, when he's pretending to be the bear while Elmer is playing dead, he stops to tell the audience "Funny situation, ain't it?"
- Creator Thumbprint: Of a creator who isn't even credited on the film: At one point Bugs turns to the audience and says "I do this kind of stuff to him all through the picture," a line Tex Avery used in many of his cartoons. Avery is often thought to have developed the story (see the trivia page for more details), though he left before it went into production and Clampett took over.
- Credits Gag: The opening credits are done in Elmer Fudd's style of speech (i.e. Robert Clampett is Wobert Cwampett).
- Downer Ending: Elmer Fudd gets thrown in jail for vandalizing park property (namely, the sign leading into the park)—but for better or worse, Bugs and the bear somehow wound up in jail with him.
- Elmer Fudd Syndrome: Used in the title and the opening credits for a gag.
- In-Scene Title Text: The title and credits are written on the landscape.
- Mickey Mousing: Elmer's car chugs and stops in tune to the rhumba beat in the opening.
- Motion Blur: Used when Elmer and the bear are speeding between a bunch of trees.
- Playing Possum: Bugs gives Elmer the classic advice of playing dead when faced with a bear.
- Punny Name: Jellostone National Park, an obvious play on Jell-Onote and the real life Yellowstone National Park.
- Reality Ensues: Elmer gets so fed up with Bugs and the Bear, that he furiously starts chopping down the sign, only to be arrested by a park ranger for willful destruction of government property.
- Super Strength: When hastily packing up his belongings to leave, Elmer accidentally uproots a giant tree—he hastily puts it back, though.
- Temporary Bulk Change: After Elmer attempts to board up Bugs's hole, Bugs walks out and briefly becomes as fat as him while mocking how naïve he is.Bugs: Dat'll hold 'im alwight, heheheheheheh. (returns to normal) Phooey.
- Tempting Fate: Elmer Fudd at the end, when he decides to get some well-needed rest and relaxation without Bugs now that he's behind bars, only to discover that both Bugs and, for some reason, the bear have become his cellmates.
